Basicaly i can not make my mind up, i have everything bar the pistons for a forged cvh (sold my accrilite ones to go to a lower comp)

but as i was thinking about replacing them, this will be around £500+
i got thinking about doing a st170 zvh and sell my cvh block and rods ect

just looking to hear peoples thoughts on what they would go for as i can see good and bad points on both set ups.

Currently have
OFAM ECU (MS based ecu)
Focus RS Injectors
Big Valve head, ported and polished with matching inlet, 285T2 cam with adjusable pully
stage 3 T3

and a undecided bottomend at the mo, my aim is 300bhp

 

Full zetec turbo bud, mines alive now will piss 300bhp.

It did 293bhp and 311ftlb at the flywheel only running 14.5psi boost.

Unless your wanting the cvh look its a no brainer.

 

Was thinking about your set up today glad to hear your all up and running
Did debate full 16v only thing stopping me is the fact i have all freshly rebuilt cvh bits but then again i could always sell it all lol

 

16v all day long. You could buy most of the whole engine for what the Cvh head would sell for!

 

16v.......... use st170 bottom end as above.......

 

16v as above

 

As said full ZT using the ST170 bottom end for 300bhp.

 

go 16v don't bother with zvh and piper cam is crap anyway so u would need to spend 300-400 getting a newman cam and fitting it

 

That's pretty conclusive lol
Looks like ill be heading down the 16v route.

 

Any questions fire away stu, a few of us have done the conversion now.

 

The results of the poll say different though

 

thats because you s1 boys ganged up with your pitch folks lol

my view is do what has the least hassle but thats me, sick of bloody cars lol

even stu above says go 16v? the guy with the best spec cvh ever built

 

I only said it because I knew it would get you going

 

yeh yeh lol

i had too eat my own words this week as i had serious issues with mine but finally see the light at the end of the tunnel

 

You'll get there soon enough mate , I had my fair share of issues to sort with WUG

 

My Zvh is a properly speced one and it pulls like a train awesome bit of kit! And it still looking a like a RS turbo when u open the bonnet!

Something special about a 8v head mate ok 16 probably more reliable and cheaper blah blah RS turbos where built with a 8v head so keep it that way

 

yeh shit happens, decided i wanted too sell the gotech and go ofam but have had 2 shit looms in a row and my third on the way which is meant too be really good.....

so got that too fit and just have running for a bit then go ofam later.

you will need to have a blast when its done to see what i mean with zetec turbos, they just seem effortless on the road and fly

 

to be honest i would stick with a cvh if you could buy a camkit that doesnt eat its self in 5 mins and a oil pump off the shelf that works

£300 for a cam kit and its a total gamble if its going to work and the only oil pumps that dont fail are genuine ford and they have stopped selling them

a bloke on here wants £300 for one and you could build a zvh bottom end using st170 bottom end for that, but while your there because the cams are a lottery might aswell drop the 16v head on


if a car is mfi and its working, leave it, they are lovely cars upto 200bhp when they are working correctly

 

Depends on how u want the car mate.....now am not a fan standard looking s2s ie wheels etc....but zetec just don't look right in the bay...so it's cvh or zvh for me..no few boys running decent power thru cvh if built and managed properly...

 

Ma thots too m8 even tho a hate standard wheels and ride height and orange lenses

 

I think all round then 16v is going to be the best option for me at the moment at least if I want more power in the future it's going to be a better base.
Ill need to start making a list of bits to buy and get my cvh bits shifted.

 

I'll take you up on that mate , maybe next year if this York thing happens

 

it's all set mate! Just the date

I'm hoping mine will be running by York so I can go up against Mark

 

Yeh will be good mate, I got a friend coming too with budget spec like ours, so there's 3 of us plus, need to talk karlos, studabear and so on

Rosopeco : yeh defo mate

 

I can pretty much give you a list of what's needed, if silvertop, with blacktop there's a water pump mod needed on top

Pm me if you need and I will write up a list for a good 250/300bhp budget builds that "work"

 

I've got to agree with the above. ST170 bottom end with a black top head, I believe (ask Karlos or mark above) the black top head is a direct fit. I also have several base maps for that which you could try.

Rob,

 

Ill be going st170 bottom end and blacktop head.
Ill buy a 170engine and think I have a blacktop head at home already in the garage somewhere. I'm looking to get a minimum of 300bhp really and I have a new OFAM ecu ready to go.

 

My advice u can go with either but don't chase a figure
Make a drivable package

 

Rob I'm ordering a ofam soon but I'm on silvertop

 

Awesome

 

Will you have a mapp for

Silvertop 2.0
Ofab sensors
Zetec coil pack
Vxr injectors
Cosworth 4x4 t3

 

Not read all of this

So u will just ask

What gearbox are you using? With this level if power I would sort your gearbox before anything else

 

my plan is to run a ib5 with quaife diff.

 

Need a new plan lol

I would use an mtx

Bit more work to get in but worth it and will handle the power

 

Gus speaks sense, its the only thing restricting my car standard rst box I'm running is on borrowed time.
